Introduction

Routing is an essential function of network communication and it involves directing data packets from one network to another. Cisco is a leading provider of routing solutions and in this article we will explore Cisco routing protocols static routing and dynamic routing.

What are Cisco routing protocols?

Cisco  routing protocols are a set of rules that determine how data packets should be transmitted within a network. They help routers communicate with each other and ensure that data packets are efficiently delivered to their destination.


What is Cisco static routing?

Cisco static  routing is a routing method in which a network administrator manually configures the routers to send data packets to specific destinations. Static routing is simple to configure but is less flexible than dynamic routing.


What is Cisco dynamic routing?

Cisco dynamic routing is a routing method in which the routers use protocols to automatically determine the best path for data packets to reach their destination. Dynamic routing is more flexible than static routing but can be more complex to configure.


Cisco Routing Protocols

Cisco routing protocols are divided into two categories: interior gateway protocols (IGPs) and exterior gateway protocols (EGPs).


Interior Gateway Protocols (IGPs)


IGPs are used within an autonomous system (AS) to exchange routing information between routers. Cisco offers several IGPs including:

Routing Information Protocol (RIP)

RIP is a distance-vector protocol that uses hop counts to determine the best path for data packets to reach their destination. It is a simple and widely used protocol but can be slow to converge in large networks.

Open Shortest Path First (OSPF)

OSPF is a link-state protocol that uses information about the network topology to determine the best path for data packets to reach their destination. It is a more complex protocol than RIP but provides faster convergence and better scalability.


Enhanced Interior Gateway Routing Protocol (EIGRP)

EIGRP is a hybrid protocol that combines the features of both distance-vector and link-state protocols. It uses metrics such as bandwidth, delay, reliability and load to determine the best path for data packets to reach their destination.


Exterior Gateway Protocols (EGPs)

EGPs are used to exchange routing information between autonomous systems (ASes). Cisco offers several EGPs including:


Border Gateway Protocol (BGP)

BGP is the most widely used EGP and is used to connect different ASes on the internet. It uses path-vector routing to determine the best path for data packets to reach their destination.


Cisco Static Routing


Cisco static  routing is a method of routing in which the network administrator  manually configures the routers to send data packets to specific destinations. Static routing is simple to configure but is less flexible than dynamic routing.

Cisco Dynamic Routing

Cisco dynamic routing is a method of routing in which the routers use protocols to automatically determine the best path for data packets to reach their destination. Dynamic routing is more flexible than static routing but can be more complex to configure.

Dynamic routing protocols can be classified as distance-vector or link-state protocols. Distance-vector protocols such as RIP use hop counts to determine the best path for data packets to reach their destination. Link-state protocols, such as OSPF and IS-IS use information about the network topology to determine the best path.

Conclusion

Cisco routing protocols static routing, and dynamic routing are essential components of network communication. By understanding how these protocols work, network administrators can ensure that data packets are efficiently delivered to their destination.
